Chip Development in 65nm CMOS Technology for the High Luminosity Upgrade of the ATLAS Pixel Detector — Leonard Germic, Tomasz Hemperek, Tetsuichi Kishishita, Hans Krüger, •Piotr Rymaszewski, and Norbert Wermes — University of Bonn, Bonn, Germany

The LHC High Luminosity upgrade will result in a significant change of environment in which particle detectors are going to operate, especially for devices very close to the interaction point like pixel detector electronics. Challenges arising from the increased hit rate will have to be solved by designing faster and more complex readout electronics that will also have to withstand unprecedented radiation doses. Developing such integrated circuit requires a significant R&D effort and resources, therefore a joint development project between several institutes (including ours) was started. This collaboration, named RD53, aims to develop a pixel readout chip suitable for ATLAS' and CMS' upgrades using a 65nm CMOS technology. During this presentation motivations and benefits of using this very deep-submicron technology will be discussed. Most of the talk will be allocated to presenting some of the circuits designed by our group (focusing on developments connected to RD53 collaboration), along with their performance measurement results.
